Lua for Android in cocos2d-1.0.1-x-0.10.0

krystian · December 19, 2011, 6:57pm

Hi,

I’ve followed this tutorial to get ios and android projects merged:
http://gameit.ro/2011/08/creating-an-iphone-and-android-cocos2d-x-hybrid-project

And it worked fine.
Now I wanted to add lua support, so I did and it works fine for iOS, however I cannot do it for Android.
I’ve followed this description:

But it was made for earlier version of cocos and it doesn’t seem to work for me.
I’m getting this:

Compile++ thumb  : game_logic <= AppDelegate.cpp
In file included from jni/../../Classes/AppDelegate.cpp:1:
jni/../../Classes/AppDelegate.h:5:23: error: LuaEngine.h: No such file or directory

make: *** [obj/local/armeabi/objs-debug/game_logic/AppDelegate.o] Error 1

Although I have:
$(LOCAL_PATH)/…/…/…/libs/lua/cocos2dx_support
defined in LOCAL_C_INCLUDES in my jni/Android.mk file.

Any tips?

Thanks

The path is error.
Did you copy cocos2dx/lua into libs?

krystian · December 20, 2011, 1:02am

<project_root>/libs/lua/cocos2dx_support/
its the correct path and LuaEngine.h is in there

krystian · December 20, 2011, 1:05am

Ahh this one is silved. I was missing these paths in /Classes/Android.mk file.
Now I’m getting this though:

SharedLibrary  : libgame_logic.so
./obj/local/armeabi/objs-debug/game_logic/AppDelegate.o: In function `LuaEngine':
/Users/krystian/ogsClient/android/jni/../../Classes/../libs/lua/cocos2dx_support/LuaEngine.h:31: undefined reference to `vtable for LuaEngine'

It seems that you have pass through compiling phase, and have trouble in liking.
I think you should check that:

Did liblua.so built successfully?
Was link path correct?

krystian · December 20, 2011, 6:58am

Well I do have liblua.so built in my libs directory under android .
I am lost on everything else though.

I’ll paste my setup, hopefully it will be something stupid and easy to spot.

Here’s my

I think I find the error in Classes/Android.mk:

LOCAL_C_INCLUDES := $(LOCAL_PATH)/../libs/cocos2dx \
                    $(LOCAL_PATH)/../libs/cocos2dx/platform \
                    $(LOCAL_PATH)/../libs/cocos2dx/include \
        $(LOCAL_PATH)/../libs/cocos2dx/lua_support \
                    $(LOCAL_PATH)/../libs/CocosDenshion/include \
        $(LOCAL_PATH)/../Classes \
        $(LOCAL_PATH)/../libs/lua_support \
        $(LOCAL_PATH)/../libs/lua/lua \
        $(LOCAL_PATH)/../libs/lua/tolua \
        $(LOCAL_PATH)/../libs/lua/cocos2dx_support \
        $(LOCAL_PATH)/../libs/lua/CocosDenshion_support

Here, $(LOCAL_PATH) is the path of Class, I think you should change it to $(LOCAL_PATH)/…/android/libs/…

BTW: You can simplify android/jni/helloworld/Android.mk. It should only link libcocos2d.so and libgame_logic.so.
You can refer HelloLua/android/jni/helloworld/Android.mk for detail info.

Hi Minggo, thanks for reply.
I am not sure, however, what do you mean

I’ve tried changing LOCAL_PATH to:
LOCAL_PATH := $(call my-dir)
LOCAL_PATH := $(LOCAL_PATH)/…/android/libs/…

But then it would throw:

Gdbserver      : [arm-linux-androideabi-4.4.3] libs/armeabi/gdbserver
Gdbsetup       : libs/armeabi/gdb.setup
Install        : libcocos2d.so => libs/armeabi/libcocos2d.so
Install        : libcocosdenshion.so => libs/armeabi/libcocosdenshion.so
Install        : liblua.so => libs/armeabi/liblua.so
make: *** No rule to make target `jni/../../Classes/../android/libs/.../AppDelegate.cpp', needed by `obj/local/armeabi/objs-debug/game_logic/AppDelegate.o'.  Stop.

I also tried changing all the paths in LOCAL_C_INCLUDES to:

LOCAL_C_INCLUDES := $(LOCAL_PATH)/../android/libs/../../libs/cocos2dx \
                    $(LOCAL_PATH)/../android/libs/../../libs/cocos2dx/platform \
                    $(LOCAL_PATH)/../android/libs/../../libs/cocos2dx/include \
        $(LOCAL_PATH)/../android/libs/../../libs/cocos2dx/lua_support \
                    $(LOCAL_PATH)/../android/libs/../../libs/CocosDenshion/include \
        $(LOCAL_PATH)/../android/libs/../../Classes \
        $(LOCAL_PATH)/../android/libs/../../libs/lua_support \
        $(LOCAL_PATH)/../android/libs/../../libs/lua/lua \
        $(LOCAL_PATH)/../android/libs/../../libs/lua/tolua \
        $(LOCAL_PATH)/../android/libs/../../libs/lua/cocos2dx_support \
        $(LOCAL_PATH)/../android/libs/../../libs/lua/CocosDenshion_support

but since it does point to the exact same place it throws the same error as before:

Gdbserver      : [arm-linux-androideabi-4.4.3] libs/armeabi/gdbserver
Gdbsetup       : libs/armeabi/gdb.setup

krystian · December 28, 2011, 4:09am

uhhhh

just for future reference…
instead of fiddling with some old howtos and tutorials just copy the Android.mk and Application.mk files from HelloLua directory to your project and adjust the paths.
I was missing all the lua *.cpp files in LOCAL_SRC_FILES
